Abstract

Proposed is a process for abrading material in pipes at junctions where branch pipes join main pipes, using a device which has a tool carrier which can be mounted in a pipe and a deposit-removal head which can be displaced with respect to the carrier and is fitted with an abrading tool, the device being designed in particular for breaking through the wall of a liner placed in the main pipe. The process is characterized in that the abrasion is carried out from inside the branch pipe in the direction of the junction, preferably in such a way that in the abrasion zone a clearance and material-discharge direction is maintained corresponding to that of the branch pipe. The invention also includes an abrading device suitable for carrying out the process.
